Description

Technical Field

[0001] The present invention relates to the technical field of granular material feeding and conveying devices, and particularly relates to a uniform feeding device for fragile materials. Background Art

[0002] A sorting machine is a device that automatically sorts target particles in granular materials based on the differences in the visual characteristics of the materials by using optoelectronic detection technology.

[0003] Sorting machines have been widely used in industries such as grain, food, plastics, and chemical engineering. Especially in the production process of processing flow lines for nuts, medium and small fresh fruits and vegetables, etc., their high-efficiency advantages are particularly obvious. Some materials in the existing market (such as walnut kernels, dried shiitake mushrooms, badam nuts, red dates, etc.) have easily broken skins. The traditional feeding method is that all the materials rush under the camera, which is likely to cause the camera not to recognize or misrecognize, and during the sorting and feeding process, it is likely to cause material mixing, resulting in backfeeding and thus requiring sorting multiple times, which is time-consuming and laborious, affects production capacity, and more seriously damages the surface of the materials. Summary of the Invention

[0004] To solve the technical problems existing in the background art, the present invention proposes a uniform feeding device for fragile materials.

[0005] A uniform feeding device for fragile materials proposed by the present invention includes a frame, and an upper feeding vibration mechanism, an upper feeding climbing and conveying mechanism, a vibrating feeding mechanism, and a vibrating material feeding mechanism are arranged on the frame;

[0006] The upper feeding vibration mechanism is used for horizontally vibrating the materials onto the upper feeding climbing and conveying mechanism;

[0007] The height of the vibrating feeding mechanism is higher than that of the upper feeding vibration mechanism and is located at the discharge end of the upper feeding climbing and conveying mechanism;

[0008] The vibrating feeding mechanism includes a first vibrator installed on the frame and a feeding hopper installed on the first vibrator. The feeding end of the feeding hopper is used to receive the materials discharged from the climbing and conveying mechanism. An elastic pressing leather is also arranged on the frame. The elastic pressing leather is located above the feeding hopper, and the end of the elastic pressing leather contacts the bottom surface of the feeding hopper;

[0009] The vibrating material feeding mechanism includes a second vibrator installed on the frame and a material feeding hopper installed on the second vibrator. The material feeding hopper is provided with a conveying groove for conveying single-row materials. It should be noted that in some embodiments, the conveying groove is a V-shaped structure.

[0010] Preferably, the elastic pressure belt includes a connecting portion connected to the frame. The lower end of the connecting portion has a plurality of pressure bars, and the plurality of pressure bars are distributed along the width direction of the connecting portion, and a deformation gap is formed between any two adjacent pressure bars.

[0011] The pressure bars gradually incline downward from the side far away from the discharge end of the feed hopper to the side close to the feed hopper, and the ends of the pressure bars are in contact with the feed hopper, which is convenient for uniform processing of the material and avoids material stacking in the vertical direction.

[0012] Preferably, a pulling member is provided between the connecting portion and the feed hopper. Further increasing the movement of the elastic pressure belt relative to the material can avoid material sticking and achieve a more effective uniform effect on the material. Preferably, the vibration frequencies of the first vibrator and the second vibrator are different, so that the setting of the pulling member further increases the effect of material uniformity and avoids material accumulation.

[0013] Preferably, the height of the connection position of the pulling member with the feed hopper is higher than the height of the connection position of the pulling member with the connecting portion.

[0014] Preferably, the thickness of the pressure bar gradually becomes thinner from the side close to the connecting portion to the side far away from the connecting portion.

[0015] Preferably, a receiving hopper is further provided on the frame. The feed end of the receiving hopper is opposite to the discharge end of the feeding climbing conveyor mechanism, and the discharge port of the receiving hopper is opposite to the feed hopper.

[0016] Preferably, an elastic discharge frame extending to the feed hopper is provided at the discharge port, and the elastic discharge frame has a portion in contact with the elastic pressure belt.

[0017] Preferably, a sensor for detecting the height of the material in the hopper is provided on the receiving hopper.

[0018] Preferably, the feeding vibration mechanism includes a third vibrator installed on the frame. A feeding hopper is installed on the third vibrator, and the discharge end of the feeding hopper is located above the feeding end of the feeding climbing conveyor mechanism.

[0019] Preferably, the feeding climbing conveyor mechanism includes a conveyor belt, and partition plates are provided on the conveyor belt. There are multiple groups of partition plates, and the multiple groups of partition plates are distributed along the conveying direction of the conveyor belt, and a transmission groove is formed between any two adjacent groups of partition plates.

[0020] Preferably, a feeding mechanism is further provided on the frame, and the material enters the feeding end of the feeding vibration mechanism through the feeding mechanism.

[0021] In the present invention, a uniform feeding device for fragile materials is proposed. The material is initially vibrated and dispersed by a vibrating material mechanism, and then homogenized by an elastic pressing leather and a first vibrator to prevent material adhesion and avoid material breakage. Then, the material is vibrated and fed by a second vibrator and a feeding hopper. Through the above structure, while facilitating the uniform feeding of the material, the material is protected to prevent damage to the surface of the material.

[0022] Additional aspects and advantages of the present invention will be given in part in the following description, become apparent in part from the following description, or be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar symbols represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0033] As Figures 1-6 shown, a uniform feeding device for fragile materials includes a frame 1, on which a feeding vibration mechanism 2, a feeding climbing conveyor mechanism 3, a vibration feeding mechanism 4, and a vibration feeding mechanism 5 are provided, where:

[0034] The feeding vibration mechanism 2 is used to horizontally vibrate the materials onto the feeding climbing conveyor mechanism 3;

[0035] The height of the vibration feeding mechanism 4 is higher than that of the feeding vibration mechanism 2 and is located at the discharge end of the feeding climbing conveyor mechanism 3;

[0036] As Figure 2 shown, the vibration feeding mechanism 4 includes a first vibrator 40 installed on the frame 1 and a feeding hopper 41 installed on the first vibrator 40. The feeding end of the feeding hopper 41 is used to receive the materials discharged from the climbing conveyor mechanism. An elastic pressing leather 6 is also provided on the frame 1. The elastic pressing leather 6 is located above the feeding hopper 41, and the end of the elastic pressing leather 6 is in contact with the bottom surface of the feeding hopper 41. The elastic pressing leather 6 is made of an elastic material such as rubber;

[0037] As Figure 3 shown, the vibration feeding mechanism 5 includes a second vibrator 50 installed on the frame 1 and a feeding hopper 51 installed on the second vibrator 50. The feeding hopper 51 has a conveying groove 510 for conveying single-row materials. At least two groups of conveying grooves 510 are opposite to one feeding hopper 51. The conveying groove 510 is a V-shaped groove. There are a first guiding slope 511 and a second guiding slope 512 between two adjacent conveying grooves 510. The included angle between the first guiding slope 511 and the second guiding slope 512 is smaller than the included angle between two adjacent side surfaces of the two V-shaped grooves. If the materials falling between the first guiding slope 511 and the second guiding slope 512 fall into the conveying groove 510 under the action of the second vibrator 50 and the self-gravity of the materials.

[0038] Place the material on the feeding vibrating mechanism 2. The feeding vibrating mechanism 2 preliminarily breaks up the material and transports it to the feeding climbing conveyor mechanism 3. The feeding climbing conveyor mechanism 3 transports the material from a lower position to a higher position and transports the material into the vibrating feeding mechanism 4. The vibrating feeding mechanism 4 vibrates and breaks up the material while applying a downward force to the material on the vibrating feeding mechanism 4 through the elastic pressing leather 6. Under the action of the first vibrator 40, the material is further broken up to avoid material adhesion and at the same time prevent material breakage. The material discharged from the vibrating feeding mechanism 4 is discharged into the vibrating feeding mechanism 4. The vibrating material mechanism vibrates and feeds the material, realizing the single-line distribution of the material in the conveying trough 510, which is convenient for the identification and screening of the subsequent material.

[0039] As Figure 4 shown. Specifically, the feeding vibrating mechanism 2 includes a third vibrator 20 installed on the frame 1. A feeding hopper 21 is installed on the third vibrator 20. The discharge end of the feeding hopper 21 is located above the feeding end of the feeding climbing conveyor mechanism 3.

[0040] As Figure 2 shown. Preferably, the elastic pressing leather 6 includes a connecting portion 60 connected to the frame 1. The lower end of the connecting portion 60 has a plurality of pressing strips 61. The plurality of pressing strips 61 are distributed along the width direction of the connecting portion 60, and a deformation gap is formed between any two adjacent pressing strips 61. The pressing strips 61 gradually incline downward from the side away from the discharge end of the feeding hopper 41 to the side close to the feeding hopper 41, and the end of the pressing strip 61 is in contact with the feeding hopper 41, which is convenient for the homogenization treatment of the material and avoids material stacking in the vertical direction.

[0041] Preferably, the position of the connecting portion 60 relative to the frame 1 in the height direction can be adjusted to adjust the height of the elastic pressing leather 6 according to different materials, thereby avoiding material breakage. In this embodiment, the connecting portion 60 is fixed to the frame 1 through a locking member. The connecting portion 60 is provided with an installation groove in the length direction. The locking member passes through the installation groove and abuts against the connecting portion 60 outside the installation groove. The locking member can be a locking screw, a locking bolt, etc. in the prior art. Loosen the locking of the connecting portion 60 by the locking member, then move the connecting portion 60 up and down to realize the sliding of the locking screw relative to the installation groove, and then rotate the locking member to fix and lock the connecting portion 60.

[0042] As Figure 7As shown, in some embodiments, preferably, a pulling member 7 is provided between the connecting portion 60 and the feeding hopper 51. When the first vibrator 40 and the second vibrator 50 vibrate, the pulling of the elastic pressure material skin 6 is realized through the pulling member 7, so as to realize the vibration of the elastic pressure material skin 6, further increasing the relative movement of the elastic pressure material skin 6 with respect to the material, thereby avoiding the sticking of the material and realizing a more effective uniform effect on the material. Preferably, the vibration frequencies of the first vibrator 40 and the second vibrator 50 are different, and through the setting of the pulling member 7, the effect of material uniformity is further increased, and at the same time, the accumulation of materials is avoided. The pulling member 7 can be a pulling rope.

[0043] As Figure 7 shown preferably, the height of the connection position of the pulling member 7 with the feeding hopper 51 is higher than the height of the connection position of the pulling member 7 with the connecting portion 60, increasing the action range of the elastic pressure material skin 6 and avoiding the accumulation of materials on the premise of increasing the material loosening effect. Specifically, two columns 14 are provided on the feeding hopper 51, the columns 14 are connected to the pulling member 7, and there are two groups of columns 14. There are two groups of pulling members 7. One group of pulling members 7 is arranged between one group of columns 14 and the connecting portion 60. The distance between the two groups of columns 14 is greater than the width of the connecting portion 60, further increasing the loosening effect on the material.

[0044] Preferably, the thickness of the pressure material strip 61 gradually becomes thinner from the side close to the connecting portion 60 to the side away from the connecting portion 60, further increasing the loosening effect on the material and avoiding material breakage.

[0045] As Figure 5 shown preferably, a receiving hopper 8 is further provided on the frame 1. The feeding end of the receiving hopper 8 is opposite to the discharging end of the feeding climbing conveying mechanism 3, and the discharging port of the receiving hopper 8 is opposite to the feeding hopper 41. Preferably, an elastic gasket 9 is provided on the side wall of the receiving hopper 8. The greater the mass of the material, the greater its inertia. If the adhered material is discharged from the feeding climbing conveying mechanism 3 and collides with the elastic gasket 9 due to its large mass, the loosening of the material is realized on the premise of not affecting its external breakage.

[0046] As Figure 8Preferably, in some embodiments, an elastic discharge frame 10 extending to the feed hopper 41 is provided at the discharge port of the receiving hopper 8. The elastic discharge frame 10 is located above the bottom of the feed hopper 41. The elastic discharge frame 10 is made of an elastic material such as rubber, and an elastic extension 11 made of an elastic material such as rubber is provided below the elastic pressing frame. The elastic extension 11 contacts the side wall of the feed hopper 41. When the feed hopper 41 vibrates, the elastic extension 11 is vibrated, thereby driving the elastic discharge frame 10 to vibrate, further realizing the further vibration and loosening of the material. Preferably, there are two groups of elastic extensions 11. The two groups of elastic extensions 11 are opposite and parallel. One group of elastic extensions 11 contacts the first side wall of the feed hopper 41, and the other group of elastic extensions 11 contacts the second side wall of the feed hopper 41. The first side wall and the second side wall are parallel and opposite. Specifically, there is a gap between the side surface of the elastic discharge frame 10 and the side surface of the feed hopper 41, increasing the service life of the elastic discharge frame 10 and the elastic extension 11.

[0047] Preferably, in some embodiments, during the working process, the elastic pressing leather 6 is in a state of contacting the elastic discharge frame 10. The pulling member 7 pulls the elastic pressing leather 6 to realize the collision of the elastic pressing leather 6 against the elastic discharge frame 10, further increasing the effect of loosening the material.

[0048] As Figure 5 shown, preferably, a sensor 12 for detecting the height of the material in the hopper is provided on the receiving hopper 8. The sensor 12 can be a distance sensor 12.

[0049] Preferably, the feeding climbing conveying mechanism 3 includes a conveyor belt 30. Partition plates 31 are provided on the conveyor belt 30. There are multiple groups of partition plates 31, and the multiple groups of partition plates 31 are distributed along the conveying direction of the conveyor belt 30. A conveying groove is formed between any two adjacent groups of partition plates 31, further facilitating the conveying of the material.

[0050] As Figure 6 shown, preferably, in some embodiments, there are two groups of feeding vibration mechanisms 2. The two groups of feeding mechanisms are distributed along the width direction of the conveyor belt 30 and are located on the same side of the conveyor belt 30. It further includes a feeding hopper 13. The feeding hopper 13 includes a receiving portion and two feeding channels communicating with the receiving portion. One feeding channel communicates with the feeding hopper 21 of one feeding vibration mechanism 2, and there is a feeding inclined surface between the two feeding channels. The feeding inclined surface is used to guide the material.

[0051] Preferably, there are two sets of vibration feeding mechanisms 4 and two sets of vibration material conveying mechanisms 5. The two sets of vibration feeding mechanisms 4 are also distributed along the width direction of the conveyor belt 30, and the two sets of vibration material conveying mechanisms 5 are also distributed along the width direction of the conveyor. The material receiving hopper 8 includes a main material receiving part and two material distributing parts. The two material distributing parts are located below the main material receiving part and communicate with the main material receiving part. The material of one material distributing part enters the feeding hopper 41 of one vibration feeding mechanism 4. The main material receiving part is used to receive the material discharged by the feeding climbing conveyor mechanism 3. A guiding inclined surface is provided between the two material distributing parts, and the guiding inclined surface is used to guide the material.
